(S,R,S)-AHPC-PEG3-NH2 hydrochloride is a VHL E3 ligase ligand-linker conjugate that combines a stereodefined AHPC VHL ligand with a three-unit polyethylene glycol linker terminating in a primary amine. Supplied as the hydrochloride salt, it is intended as a research building block for PROTAC synthesis and other chemical biology applications.
- Hydrochloride salt form for improved handling.
- Primary amine terminus suitable for common coupling chemistries.
- Three-unit PEG linker provides aqueous solubility and flexible spacing.
- Stereochemically defined (S,R,S) VHL ligand for targeted E3 ligase engagement.
- High reported purity (~99.0%) for reliable synthetic use.
- Available in small to gram-scale quantities for research workflows.
